i'm asking again:

how can i detect that ELF Image is NetBSD and not FreeBSD other way than
checking memory for "NetBSD foundation" string?

i already patched etherboot to work this way so it loads now NetBSD kernel
cleanly and passes memory sizes right (right bootinfo will be done too),
but this way of detection is just stupid.
